    Comedy Thread

    An extremely modest man was in the hospital for a series of tests, the last of which had left his bodily systems extremely upset. Upon making several false alarm trips to the bathroom, he decided the latest episode was another and stayed put. He suddenly filled his bed with diarrhea and...

    Each diode tested must be disconnected from circuitry. You can either lift one lead to get it disconnected from circuitry or just pull the diode completely. Then use the diode test function on DVM to see what Vf voltage shows in one direction of the placing of the two test leads across the...

    How does a Battery management board work?

    AprilSteel . . . . . On this board depicted, it shows the taking of individual cell voltage samples in from the lines at the left and going into the U 23 thru 29 buffer stages and then visually having LED indications and also passing samplings on into two vertical clusters of series...

    Sir zio_mangrovia . . . . . Using the available schematic for that board really shows its shortcomings in the lazy person only having composed it as being separate circuit islands with no intermediary interconnects. I replotted it just enough to include all of the interconnects and circuit...

    Open a Gate remotely using a wifi relay

    Sir jacobsdad . . . . . Oh tayyyyyyyy . . .then. Why not go for this Garage Door Opener unit and let it become a Gate Door Opener . It gives you WI FI options of Alexa-Echo-Nest voice control via Android or Apple OR it gives you a 433mhz RF push button hand held transmitter. The units single...

    Open a Gate remotely using a wifi relay

    Is the gated entrance basically for car/motorcycle/bike entry, or would a walking pedestrian also be sometimes considered ? Is there an intercom to the office at the gate proper ? (Or is that being the WiFi aspect? ) Do you have visual view of the gate in order to see when it is "safe" to close...

    I have to replace too: C705, C706, C766, C768. I have to replace only C766 and C768? The C766 and C768 are common electrolytic capacitors, susceptible to timely failures by the high demands being made upon them. The C705, C706, C766, C768 are of a different construction and more rugged type of...

    Sir zio_mangrovia . . . . . In the 4 J-K area, associated with your L710-L711 inductors, you ALSO have the capacitor cluster of C766 and C768, that have to be up to full capacitance. And lastly, back at the origin of the switch mode drives generation, at IC700, you have C715 which is the...

    Inductor coil question

    Sir Faderz . . . . . OK . . . . you initially had the majority of the mindsets here all keyed up and expecting some inductor related to speaker crossover networks passages and their bypass characteristics related to the adjunct capacitance being used. That is . . . .until that meager 25 uh...

    Must unplug and replug power to make Cooker Hood / Kitchen-Fan work

    Sir carlsweden . . . Your selective disconnects of the lamps and then the fan seems to signify neither lamp overload or motor loading to be at fault. NOW Go to this site: http://www.cylinda.se/produkt/kok/flaktar/9004341# Play the top right . . . . . EASYCLEAN. This relates to two aspects...

    Why do you name this area as 4K ? Look at the extreme left side of the schematic to find the 4 position. Look at the extreme top of the schematic to find the K position. Now extend the 4 position to the right and the K position directly down the schematic and they intersect in our standby...

    DEFY magnetron - stuck with removal?

    Sir FuZZ1L0G1C . . . . . I was hoping to be finding a dimensional drawing of the build of that series of units . . . no findee . . . but this might suffice, instead. Photo 1 . . . . .You can see the maggie output probe and its RFI / Grounding mesh and the two RED LINED mounting holes which...

    Sir zio_mangrovia . . . . . Your basic 2 supply voltages out of that units power supply are +24VDC and +12VDC at schema AREA 5-F/G. The +24 is being related to backlight supply. Your lower supply voltages are being derived from the basic +12. BE SURE that ALL of the C729-730-731 E-caps...

    Adapting power output

    Messr jujuteux . . . . . Appeler un chat un chat . . . .do you think that those fans will even CARE about receiving an extra 0 .7 Volt ? I know that the pump MOTOR, will just love it. If that battery that you specify, is being a "pouch" type Li ion battery, a hard metal cased 18650 would be...

    Realistic STA-2100D

    Sir tomcat65 . . . . . The volume and balance control are supposed to be "clutched" together. You bring up the volume knob up to a high enough mono source evaluative level and then adjust the separate balance where both speaker channels then equate in level . Thereafterwards, as the volume...

    Sir Carl from Sweden . . . . . If being a "sophisticated /involved" problem, it will involve the non existant . .as to date . . . actual schematic of the GREEN board circuitry. Prior to seeking that out . . . . it sort of suggests of a possibility of a power loading problem. If being the 12V...
